Executive Summary

The Strait of Hormuz has effectively shut down following the military conflict with Iran that began 28 February 2026, removing ~11–13 million barrels per day (mb/d) from global oil markets — equivalent to roughly 20% of global supply — with ship transits collapsing from ~130/day to ~6/day. The EIA projects shut-ins peaking in April 2026 and gradually abating into late 2026 if the conflict resolves quickly, while the Dallas Fed models a multi-quarter recovery timeline with three distinct scenarios. ADNOC CEO al-Jaber states full Hormuz flows unlikely before Q1–Q2 2027 even if conflict resolved immediately.

Key Findings

1. Immediate Physical Disruption: Near-Total Hormuz Closure

  • WTO AIS tracker shows outbound crude oil, LNG, and fertilizer shipments collapsed from ~130 ships/day to ~6 ships/day — a ~95% drop. (WTO Strait of Hormuz Trade Tracker)
  • Wood Mackenzie (May 2026): 11+ mb/d Gulf crude and condensate production curtailed — confirmed across multiple institutional sources. (Wood Mackenzie Horizons Report)
  • Exxon SVP Neil Chapman (May 28): "We're approaching unheard of inventory levels. I mean, really, really low levels." Conflict has removed 12–13 mb/d from global markets. (CNBC / Bernstein Conference)
  • IEA (May 13): "Largest supply disruption in history of global oil market." Strait closure has cost market more than 1 billion barrels. (IEA OMR May 2026)

2. Country-Level Shut-In Data (April–May 2026)

Country Shut-in (mb/d) % Capacity Key Risk
Iraq 2.82 ~62% Southern export terminal blockade
Saudi Arabia 1.90 ~16% East-West pipeline at capacity
Kuwait 1.25 ~45% Total Hormuz dependency
UAE 1.11 ~28% Fujairah ADCOP terminal damage
Qatar ~0.60 ~40% Ras Laffan LNG/Condensate outage
Iran ~1.60 ~50% Kharg Island strikes
Kazakhstan ~1.20 ~70% CPC pipeline sabotage

Source: EIA April 2026 STEO + BP Ramsay CERAWeek briefing. Kazakhstan's CPC pipeline (carrying 70% of Kazakh crude exports) suffered sabotage damage requiring 3-5 years to repair — effectively removing these barrels from the short-term recovery outlook.

3. Demand Destruction Layers

The supply shock is now triggering demand-side destruction — the market is losing supply AND demand simultaneously:

Layer Data Point Source
China retail gasoline -20% YoY (April 2026) Goldman Sachs (Jun 1)
Western Europe retail fuel -8% YoY (April 2026) Goldman Sachs (Jun 1)
Global inventory draw 8.7 mb/d in May (record) Goldman Sachs / Exxon
OECD operational stress Early June 2026 JPMorgan
Consumer behavior Travel delays, petrochemical production cuts Goldman Sachs

Goldman Sachs pivot: First major sell-side bank to flag demand destruction as now the dominant story alongside supply disruption. EVs, urban transport in China, and work-from-home have increased "switching opportunities." Brent could trade $10/bbl below forecast if China/Europe demand weakness persists. (Goldman Sachs via Business Insider, Jun 1)

4. OPEC+ Response: Symbolic, Not Structural

  • 188,000 bpd increase for June — ~1.5% of the 12–13 mb/d Hormuz disruption. (OPEC+ / CNBC, May 3)
  • First meeting without UAE — departed OPEC effective May 1, 2026. UAE was OPEC's third-largest producer.
  • 7 countries remaining: Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, Oman
  • Without UAE, OPEC+ has less spare capacity to deploy if Hormuz reopens — structural constraint on supply response.

5. Recovery Timeline: Months to Years

  • ADNOC CEO al-Jaber (May 28): "At least four months to get back to 80% of pre-conflict flows, and full flows will not return before the first or even second quarter of 2027." Even if conflict resolved immediately, physical production recovery takes months. (CNBC / Bernstein)
  • Chevron CEO Wirth (May 28): "Damage to oil and gas infrastructure in the Middle East will cost tens of billions of dollars to repair."
  • JPMorgan: "Duration dominates scale — prolonged disruption cannot be absorbed like temporary one." (Rigzone, May 13)

6. Diplomatic Timeline

  • April 7, 2026: Trump set deadline for Tehran to reopen Hormuz, warned of "Total Regime Change."
  • April 7 ceasefire: Iran agreed to provisional reopening under "Iranian management" — $2M/vessel transit fee.
  • May 23, 2026: Trump announced proposed framework agreement — 60-day ceasefire extension, Hormuz reopening, Iran permitted to sell oil freely. Not yet signed as of June 1.
  • Goldman Sachs base-case: 6-week core Hormuz blockade → cumulative oil losses exceeding 800 million barrels.

7. Historical Context: The Largest Disruption in Modern History

Event Global Supply Lost
Yom Kippur War (1973) ~6%
Iranian Revolution (1979) ~4%
Persian Gulf War (1990) ~6%
COVID demand shock (2022) ~3%
Current Hormuz closure (2026) ~20%

This disruption is 3–5× larger than any prior geopolitical oil supply event in the modern era. (Dallas Fed)

8. Duration Scenarios (Dallas Fed Model)

Scenario Q2 Q3 Q4 Q4/Q4 GDP Impact
1 quarter (reopens Q3) WTI $98/bbl WTI $68/bbl WTI $67/bbl −0.2%
2 quarters (reopens Q4) WTI $98/bbl WTI $115/bbl WTI $76/bbl −0.3%
3 quarters (reopens Q1 2027) WTI $98/bbl WTI $115/bbl WTI $132/bbl −1.3%

Global real GDP impact Q2 2026: −2.9% annualized in all scenarios. (Dallas Fed)

Confidence Assessment

Factor Rating Reasoning
Shut-in volume (11–13 mb/d) HIGH Multiple institutional sources converge (WoodMac, Exxon, IEA)
ADNOC recovery timeline (Q1-Q2 2027) HIGH Operator statement — operational reality, not speculation
Demand destruction (China -20%, Europe -8%) HIGH Goldman Sachs hard data from April 2026
OPEC+ symbolic increase (188K bpd) HIGH Official OPEC+ decision
Duration scenarios MEDIUM Dallas Fed model is rigorous but assumes rational actor closure dynamics

Overall Confidence: HIGH — Quantitative disruption data is solid from multiple independent sources. Recovery timeline is the most concrete from any industry source.
